摘要: The effect of water temperature on white-spotted conger activity was examined using acoustic accelerometer transmitters to understand thermal effects the behavior a target fishery species. We recorded swimming activities 21 congers video cameras and compared body undulation frequency with acceleration values measured in cavity. found significant, positive, linear relationship between (body frequency) congers. conducted calibration trial evaluate relationships transmitters, which confirmed associated its activity. also levels. levels eight at temperatures from 10 28 °C were tested transmitters. positive 26 °C, whereas declined 26 28 °C. These results demonstrate that can quantitatively measure changes nature.
